SMOKING PIPE.

Application filed July 5,

Tol all whom z'tmay concern.'

`Be it known that I. JOSEPH I. Ln BEL, a subject of the King of Great Britain, residing at Montreal, Province -of Quebec, Canada, have invented certain new and useful Improvements in Smoking Pipes; and I do hereby declare that the following -is` a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains'to makev and use the same. y

The primary object of this invention, which is a smov ing pipe, is the provision of means for retaining moisture and nicotine from the tobacco in such a manner that the same cannot -be drawn into the mouththrough the same. The invention resides in the formation of a moisture chamber in the stem of the pipe, the chamber being formed separate from the passagev and in communication therewith through the bowl and through additional ducts.

The chamber contains a piece of absorbent material, for the insertion of which it is necessary that the stem be made in two parts. The connection between the two parts is in the nature of a at joint which does not become clogged as readily as the usual screw joint.

A. further object of the invention is a pipe so constructed that during the o eration of smoking, there will be no suctlon onv the nicotine deposited in the bowl.

Asa pipe is smoked, the tobacco is converted into a number of elements including smoke and nicotine. An additional feature of the invention lies in the fact that two of these elements, namely smoke andl nicotine, are separated in the bowl, and are subsequently revented from mixin with one another a ter separation. In thls respect, the invention is to be distinguished from other pipes, in which the smokeand nicotine are drawn together intothe stem and are supposed to separate on their way to the mout piece. l

More specifically, the invention makes use of a moisture chamber formed/in the stem of the pipe andbeneath the draft passage. InA order to avoid the entrance of nicotine and moisture into the draft passage, the interior of the bowl is provided w1th a proection disposed above the `draft passage.

this means, the moisture and nicotine avoid said draft passage'and are directed downwardly in the direction of the moisture 1928. Serial No. 649,788.

chamber, the entrance thereof being of such configuration and disposition as to readily receive the moisture andini'cotine which is urged downwardly as `the burning of4 thetobacco continues. In this connection it is to be noted that during the burning of the tobacco, the heat generated has theefl'ect of forcing the moisture and nicotine downwardly, so that the tendency of such moisture and nicotine to proceed towards the moisture chamber is positive rather than incidental. j

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal section through the pipe;

Flgure 2 is a similar view of the mouthpiece;

Figure 3 and stem; 1 j

Figure 4 is a section on vthe line 4 4 of Figure 1;

Figure -5 is an enlargeddetail section of the bowl; and,

is a similar view of the bowl Figure6 is a perspective v iew thereof,

parts vbeing broken away.

Referrin to the drawings by reference numerals, t e pipe consists of a hollow bowl 1 provided with a stem 2. A draft assage 3 is formed through the stem an communicates withthe bowl in the usual manner. A moisture chamber 4 is cut through the stem in substantially parallel relation with the draft passage, and is disposed therebeneath. This chamber also communicates with the bowl. A groove 5 formed in the front wall of the bowl and connecting the inner ends of the draft passage and molsture chamber conducts the nlcotine away from the passage and into the chamber. The mouthpiece 6 is connected to the stem by means of an abutment 7 which is threaded for en ement with the forward portion 8 o? 51e moisture chamber. The stem has formed therein the usual passage 9 which communicates with the passage 3 when the stem is turned into its proper position. The joint between the draft passages through the mouth-piece and stem i`s flat in contrast with the usual threaded joint formed in the corres ending position in other pipes. It is well known that where a screw joint occurs in the `draft passage, there is an accumulation Vof nicotine and other clogging substances. This inconvenience is eliminated by means of the at joint described above.

The stem is of substantially triangular u 1ev ter extending ing progresses.

through a corner. This construction is of light weight and of sufficient strength in spite of the draft passage and moisture chamber formed therein.

A strip of absorbentmaterial 10 is inserted in the abutment 7 and extends into the chamber 4. This material serves to take up the moisture as the latter deposits in the chamber, and can be renewed as often as desired by merely separating the mouth-piece .from the same. The chamber 4 may be provided with a tubular linin of glass, aluminum, or 'similar non-absor ent material, so that the moisture received in this chamber cannot permeate into the wooden walls.

The curvature -of the cavity in the bowl is such that there is formeda projection l above the inner end of the draft passage 3. As the result of this construction, the nicotine and moisture which are forced downwardly as the burning continues, are simultaneouslypdirected somewhat laterally in order to avoid entering the draft passage.

`Consequently this material enters the moisture chamber through the opening 5, the latbeyond the inner end of the draft passage'3, as a result of which the entrance of the moisture and nicotine into the chamber 4 is greatly facilitated.

In the ordinary use of a pipe, the burning tobacco is changed to ashes, and the moisture and nicotine from such burnt to bacco is forced downwardly into the bowl under thel action of the heat produced. Consequently, the moisture concentration of the remaining tobacco increases as the smok- Finally the concentration of .the moisture becomes so great that the tobacco at the bottom of the bowl is saturated with it, and such moisture is then drawn through the stem and mouth-piece. In the present invention, the elements produced in the burning, including the smoke, are separated in such manner that the smoke and lmoisture follow different paths, In other words, the moisture and nicotine are prevented from entering the draft passage 3 by means of the projection 1, as already ointed out. vUnder the burning of the toacco, the moisture and nicotine are forced downwardly into the openings 5, thereafter being absorbed in the chamber 4. smoke, being lighter than the moisture and nicotine, is attracted b the draft produced in the draft passage Aw ereupon it is pulled therein.- Because of the space between the inner end of the passage 3 and the opening 5, an excessive draft through the smoke passages will not lift the moisture from the chamber 4i) especially when the Asame has been absor ed in the substance 10. It has been found that even an excess of draft through the smoke passages will not raise The the moisture of the moisture chamber. In fact, it is physically impossible to raise such moisture and nicotine after the same have reached a level below thelower wall of the draft passage 3', especially when the nicotine has become absorbed in the material 10. v

As an additional feature, a duct 11 is formed in the stem near the inner end thereof and connects the smoke passage 3 with the moisture chamber, as clearly shown in Figures 1 and 3. This duct is inclined forwardly Yand is supplemented by a similar channel or duct 12 at the forward end of the stem. The functions ofthe duct l2 areas follows: (l) if the smoke passage becomes clogged at the inner end, the smokey may pass through the channel 11 and to the duct 12, whence it enters the mouth-piece 6; (2)

in the normal operationl of the pipe, any nicotine or saliva that may be carried into the smoke passage 3 has an opportunity to fall into the moisture chamber through the duct 12 before enterin the mouth-piece passage 9; and, (3) the uct 12 permits entrance of nicotine from` the intermediate portion of the draft passage into the cham-` is to be Vunderstood that various alterations" in the details vof construction may be made without departing from the spirit of the invention as indicated by the appendedclaims. u d,

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is r- 1. A smoking pipe comprising` a Abowl and a stem, said stem having formed therein -a draft passage and aA moisture chamber,

both in separate communication with the bowl, said chamber' vbeing .disposed beneath the passage, and inclined ducts connecting said passage andtmoisture `chamber near the ends thereof.

k2. A smoking pipe comprising a bowl` and i a stem, said stem having formed therein a draft passage and a moisturechamber, bothV in separate communication with they bowl, said chamber having its entrance openin disposed beyondthe inner end of the draf?. passage in the'stem, an inwardly extending projection formed within the bowl and disposed above the draft passage, and inclined ducts connecting said passage and moisture chamber near `the ends thereof.
